The ambient temperature is within the range from 0°C to 50°C.
The temperature and humidity is maintained at a constant level.
There is minimal dust and dirt in the area.
CAUTION
If the ambient temperature is outside the operating range, the battery pack stops operating to protect itself.
The optimal temperature range for the battery pack to operate is 0°C to 50°C. Frequent exposure to harsh
temperatures may deteriorate the performance and life of the battery pack.
3.3 Installation
A. Put battery modules into cabinet and connect the cables:

4. Safety Precautions
Warning
Before Connecting 1) After unpacking, please check product and packing list first, if product is damaged or lack of parts,
please contact with the local retailer;
2) Before installation, be sure to cut off the grid power and make sure the battery is in the turned-off
mode;
3) Wiring must be correct, do not mistake the positive and negative cables, and ensure no short circuit
with the external device;
4) It is prohibited to connect the battery and AC power directly;
5) The embedded BMS in the battery is designed for 48VDC, please DO NOT connect battery in series;
6) Battery system must be well grounded and the resistance must be less than 1 ;
7) Please ensured the electrical parameters of battery system are compatible to related equipment;
8) Keep the battery away from water and fire.
In Using 1) If the battery system needs to be moved or repaired, the power must be cut off and the battery is
completely shutdown;
2) It is prohibited to connect the battery with different type of battery.
3) It is prohibited to put the batteries working with faulty or incompatible inverter;
4) It is prohibited to disassemble the battery (QC tab removed or damaged);
5) In case of fire, only dry powder fire extinguisher can be used, liquid fire extinguishers are prohibited;
6) Please do not open, repair or disassemble the battery except staffs from Pylontech or authorized by
Pylontech. We do not undertake any consequences or related responsibility which because of
violation of safety operation or violating of design, production and equipment safety standards.
Reminded
1) Please read the user manual carefully (in the accessories);
2) If the battery is stored for long time , it is required to charge them every six months, and the SOC
should be no less than 80%;
3) Battery needs to be recharged within 12 hours, after fully discharged;
4) Do not expose cable outside;
5) All the battery terminals must be disconnected for maintenance;
6) Please contact the supplier within 24 hours if there is something abnormal.

5. Trouble Shooting Steps Problem determination based on: 1) Whether the battery can turn on or not;
2) If battery is turned on, check the red light is off, flashing or lighting;
3) If the red light is off, check whether the battery can charge/discharge or not.
Preliminary determination steps:
1) Battery cannot turn on, switch on the lights are all no lighting or flashing. If the battery external switch is ON, the RUN light is flashing, and the external power supply voltage is 48V or
more, the battery still unable to turn on, please contact Pylontech.
2) The battery can be turned on, but red light is lighting, and cannot charge or discharge. If the red light is lighting, that means system is abnormal, please check values as following:
a) Temperature: Above 50 or under -10 , the battery could not work.
Solution: to move battery to the normal operating temperature range between -10 and 50
b) Current: If current is greater than 100A, battery protection will turn on.
Solution: Check whether current is too large or not, if it is, to change the settings on power supply side.
c) High Voltage: If charging voltage above 54V, battery protection will turn on.
Solution: Check whether voltage is too high or not, if it is, to change the settings on power supply side.
d) Low Voltage: When the battery discharges to 44.5V or less, battery protection will turn on.
Solution: Charge the battery for some time, the red light turn off
Excluding the four points above, if the faulty is still cannot be located, turn off battery and repair.
3. The battery cannot be charged or discharged 1) Cannot be charged:
Disconnect the power cables, measure voltage on power side, if the voltage is 53~54V, restart the battery,
connect the power cable and try again, if still not work, turn off battery and contact Pylontech.
2) Unable to discharge:
Disconnect the power cables and measure voltage on battery side, if it is under 44.5V, please charge the
battery; if voltage is above 48V and still cannot discharge, turn off battery and contact Pylontech.
